Thread: How much 2stroke oil to add?

I use it. The oil glazing build up on the bores helps to offset the wear I have from using paper filters before I got a K&N.

Mercedez Benz just did it to fool everyone and give them something to moan about that.

Mercedez Benz........Hmmmmm they are a pretty average F1 maker/repeated world championship team, luxury car maker, 4x4 maker, 6x6 maker, truck maker, bus maker, Unimog etc,etc,etc

But then, this dumkopf car maker(Mercedez Benz) added 2stroke to its diesel for some unknown reason on a rally half way across the world(Paris to Beijing in 2007 with an E Class 320cdi). Why would they do such a thing??

Instead of canning the idea with no basis for your arguments than jokes or 'I reckon' type answers. 'I reckon' that nay sayers should be providing some definitive proof that 2stroke added to diesel doesn't work and that it must be proven to Australian Standards, otherwise, it just sounds to me like a bunch of backyard mechanics giving their opinion against a long term car research/developement and manufacturing industry leader.

But I forgot, a collection of backyard mechanics must know more than and could do all so much better than Mercedez Benz. Geez, 'I reckon' I've been listening to the wrong people.


Cheers,

Jason

Well this back yarder admits to trying 2- after reading on the hocus pokus on the interwieb a few years ago
With my seat of the pants Dyno testing i noticed nothing different oh and that 300tdi diesel Rattle was still the same
Maybe what you say in a lab the difference what ever it is could be noticed but for joe blow average maybe not
I think at the end of the day if you believe it so be it but with out all the technical proof some will always argue

MB added the 2 stroke oil as the quality of oil in most of the countries enroute was suspect. Didn't want an embarrassing failure due to dodgy fuel. Also didn't want to advertise this. So it for known reasons - Modern injectors can't handle lack of lubrication in fuel.

And you don't think some of ours is suspect?

Which 2 stroke, outboard, m/c or plain air cooled motor mower

Never said it wasn't. Btw: why do we accept that the fuel quality may be suspect. ie as dodgy as provided in third world countries.
Pumps used to have a sight glass to show fuel quality, due to poor quality being provided. This disappeared some 20 years or more ago. Problem hasn't gone away; a whole new industry has sprung up to protect us from dodgy fuel. Responsibility should be with the fuel retailer to provide correct quality fuel, not with each owner to protect against dodgy fuel.

Let's run a couple of controlled tests to see if it makes any difference. Mineral 2 stroke (assume for air cooled motors?) seems to be the go. Volunteers?

Testing for noise and vibration only or fuel economy as well? To make it a bit scientific consider what needs to be done.
At least two full tanks to confirm results. Controlled fuel (eg Caltex or BP) from the same servo. Need to ensure the same dosage per litre. Do we need to measure the fuel temperature when purchasing to reduce this variable? Run the same route for both tank fills to reduce this variable? Double blind testing required to get rid of any personal bias? Where do we position the dBa meter on the vehicles to reduce this variable? How do we remove ambiant noise variables? What pyros will we use? How do we record results to make a meaningful comparison? Lots of other items to consider - tyre pressures ? Haven't even got to how to measure engine vibration. And don't know what instruments are used to measure it. 😨

In the end it's your car, so if you want to try 2 stroke give it a burl. What's the worst that could happen? Injectors fail? Engine failure? Personally, I'd prefer to not experiment with my engine like this.
